Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur.
Gene flow, the introduction of genetic material (by interbreeding) from one population of a species to another, thereby changing the composition of the gene pool of the receiving population. The introduction of new alleles through gene flow increases variability within the population.
Gene flow — also called migration — is any movement of individuals, and/or the genetic material they carry, from one population to another. Gene flow includes lots of different kinds of events, such as pollen being blown to a new destination or people moving to new cities or countries.
In population genetics, gene flow (also known as migration and allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective population.
Gene flow, also called gene migration or allele flow, refers to the transfer of genetic material from one population to another during reproduction (through interbreeding) or the vertical transfer of genetic material from the parent to the offspring.
gene flow. The movement of alleles between previously separate populations caused by migration and subsequent mating.
What are ways species exchange genes with each other? Hybridization and gene flow are shortcuts to biodiversity that don’t always involve differentiation.
Gene flow is the elementary agent of evolution responsible for the dispersal of genes between two populations of the same or different species, followed by the successful establishment of the immigrant genotypes in the new population (Woodruff 2004).
Gene flow is a concept in population genetics to refer to the movement of genes or alleles between interbreeding populations of a particular species. When members of a gene pool mate with members of another gene pool it can alter the allele frequencies (which pertains to the proportion of members in a population carrying a specific variant of a ...
This article treats gene flow and migration, as used in population genetics, equivalently. Discussions of gene flow started shortly after the definition of population genetics in the early 1900s, although the term itself first appeared in 1941.
